Lately my mind is wandering in the direction of buying a new computer, preferably a laptop.
My current one is a desktop froom 2002, and although it actually works rather problemfree (now that I've said that, this error free thing will end...), a hardware upgrade is never a bad thing. Now you're gonna say, ask the computershop. But I like hearing from people who without a doubt use similar programs to me etc.
Not much into gaming, and Lascaux is by far my favourite drawing program. Although that can be because ps2 has trouble working the way I want it to (memory overdraw).
I also make a lot of photo's and plan on doing more with them. Any tips on what is important and what is not so much?

size and weight are probably important. screen resolution and color gamut are probably important.
I'm personally a fan of tablet pcs because you essentially have wacom built into your laptop (draw straight on the screen).
I would recommend 2gb ram minimum. none of the other specs will matter much if you're buying a new computer, they're all going to be more or less fast enough (especially if your computer from 2002 works fine for what you do).
Lascaux Sketch has pretty low system specs (it was designed to run fast in 2003, after all), but no saying future revisions won't have beefier (more modern) requirements.

Thanks for the info. I'd love a tablet pc, but they cost roughly 3 times as much to what I want to spend. Once at a car/motor fair somebody was designing cars on one, looked really cool.
Well with lascaux I've already run into problems come to think of it, you increased the size of the contest board and I cannot work on the max size properly out of memory etc.
2GB is can that be mentionned as 2.084 mb memory?

how much do you want to spend? There are some inexpensive tablet PCs (under 2k) if you look around.

2GB is 2048MB, yes.

I live in Europe and I think things are a liiiitle bit more expensive over here. I have seen one of Dell which costs € 1699 (about $ 2,550). And to be honest I don't want to spend over € 900 = $ 1,410. If I would be into designing as a job, rather then a hobby, it'd be well worth the investment, but for me it is a fun way to relax.
Since nobody has come up to offer me an job in the arts industry, I earn my keeps in finance.

Whatever you do, don't go with Vista, get XP. It doesn't matter how much GB of RAM you have, it will be horribly slow and just a nuisance to use. I don't particularly care for Dell, so I wouldn't go for that either. You can get plenty of decent Laptops under 1000$ Canadian... in canada anyway... I couldn't really say much for Europe. Decent enough for what you are looking for anyway.

vista is fine, I've been using it for 2 years without issue.

I have XP now on a Dell, Dell is fine with me, it has been running since 2002 fine for me now, so has XP. Have heard nasty things about Vista though, but that was when it first came out.
Decent laptops we have under € 650 (=$1000 canadian) too, but for a laptop I want I have to spend at least € 815 (=$1300 canadian).
And I was referring to the tablet PC Marcello mentionned, that we don't have cheap(er).
